このような油圧式クラッチレリーズ装置はクラッチハウジング内に配置されるが、汚れや埃などにより、油圧を保持するシール部材や当該シール部材と接する面が傷付きクラッチ操作不能となるのを防止する必要がある。そのために、特許文献１ではシリンダ部の外周にゴム性の蛇腹タイプのブーツを配置しているが、このような構成ではレリーズベアリングの作動範囲を確保するため蛇腹の折り曲げによる径方向外側のスペース、及び密着を考慮した軸方向のスペースが必要であり、装置の小型化を阻害している。   Such a hydraulic clutch release device is disposed in the clutch housing, but it is necessary to prevent the seal member holding the hydraulic pressure and the surface in contact with the seal member from being damaged due to dirt, dust, etc., and the clutch operation being disabled. There is. Therefore, in Patent Document 1, a rubber bellows type boot is disposed on the outer periphery of the cylinder portion, but in such a configuration, a radially outer space by bending the bellows in order to secure the operating range of the release bearing, In addition, a space in the axial direction in consideration of close contact is required, which hinders downsizing of the apparatus.

また、特許文献２では（収縮時に）レリーズベアリングを覆うようにシリンダ部の外側ハウジングより円筒状壁が延在しているが、フルストローク時にレリーズベアリングが外側ハウジングの円筒状壁から飛び出てしまい、円筒状壁の内側に汚れや埃などが侵入し、侵入した汚れや埃などによりシール部材を傷付ける可能性がある。また、特許文献２に記載の発明でも、特許文献１の蛇腹タイプと同様に、レリーズベアリングの径方向外側にスペースが必要であり、装置の小型化を阻害している。   In Patent Document 2, the cylindrical wall extends from the outer housing of the cylinder portion so as to cover the release bearing (when contracted), but the release bearing protrudes from the cylindrical wall of the outer housing at the time of full stroke, There is a possibility that dirt, dust or the like enters the inside of the cylindrical wall, and the sealing member may be damaged by the dirt or dust which has entered. Also in the invention described in Patent Document 2, as in the bellows type of Patent Document 1, a space is necessary on the radially outer side of the release bearing, which hinders downsizing of the device.

本発明の目的は、汚れや埃などからシール部材及びこれと接触する面を保護し、かつ、装置の小型化を実現することができる油圧式クラッチレリーズ装置を提供することである。   An object of the present invention is to provide a hydraulic clutch release device that protects a seal member and a surface in contact with the seal member from dirt, dust, and the like and that can realize downsizing of the device.

The second cylindrical member 22 is compressed and supported by a compression ring 21 that is externally fitted to the first cylindrical member 20.

次に、実施形態１に係る油圧式クラッチレリーズ装置の動作について説明する。まず、クラッチペダル（図示せず）を踏み込み操作すると、クラッチマスタシリンダ（図示せず）から油通路１２ｂを通じて油圧室１７へ圧油が供給され、油圧室１７内の油圧が高まる。そして、油圧室１７内の油圧が高められると、ピストン部材１３がダイヤフラムスプリング（図示せず）側に向けて移動（摺動）する。このピストン部材１３の移動は、レリーズベアリング１８を介してダイヤフラムスプリング（図示せず）の中心部に伝わり、ダイヤフラムスプリング（図示せず）がクラッチディスク（図示せず）とフライホイール（図示せず）との接合を解除するように弾性変形する。このとき、ピストン部材１３の移動によってレリーズベアリング１８を介して第１の円筒状部材２０もダイヤフラムスプリング（図示せず）側に向けて移動（摺動）する。また、第２の円筒状部材２２は、圧縮リング２１によって圧縮支持されているので、第１の円筒状部材２０の移動に追従する。   Next, the operation of the hydraulic clutch release device according to the first embodiment will be described. First, when a clutch pedal (not shown) is depressed, pressure oil is supplied from a clutch master cylinder (not shown) to the hydraulic chamber 17 through the oil passage 12b, and the hydraulic pressure in the hydraulic chamber 17 increases. When the hydraulic pressure in the hydraulic chamber 17 is increased, the piston member 13 moves (slides) toward the diaphragm spring (not shown). The movement of the piston member 13 is transmitted to the central portion of a diaphragm spring (not shown) via a release bearing 18, and the diaphragm spring (not shown) is moved to a clutch disk (not shown) and a flywheel (not shown). It is elastically deformed to release the joint. At this time, the movement of the piston member 13 causes the first cylindrical member 20 to move (slid) toward the diaphragm spring (not shown) via the release bearing 18. Further, since the second cylindrical member 22 is compressed and supported by the compression ring 21, it follows the movement of the first cylindrical member 20.

一方、クラッチペダル（図示せず）の踏み込みを解除すると、油圧室１７に供給された圧油は、油通路１２ｂを介して排出される。これにより、ピストン部材１３がダイヤフラムスプリング（図示せず）の反対側に向けて移動（摺動）する。このピストン部材１３の移動は、ダイヤフラムスプリング（図示せず）がクラッチディスク（図示せず）とフライホイール（図示せず）とを接合させる。このとき、ピストン部材１３の移動によってレリーズベアリング１８を介して第１の円筒状部材２０もダイヤフラムスプリング（図示せず）の反対側に向けて移動（摺動）する。また、第２の円筒状部材２２は、第１の円筒状部材２０の移動に追従する。   On the other hand, when the depression of a clutch pedal (not shown) is released, the pressure oil supplied to the hydraulic chamber 17 is discharged through the oil passage 12b. As a result, the piston member 13 moves (slids) toward the opposite side of the diaphragm spring (not shown). The movement of the piston member 13 causes a diaphragm spring (not shown) to join a clutch disk (not shown) and a flywheel (not shown). At this time, the movement of the piston member 13 causes the first cylindrical member 20 to move (slide) toward the opposite side of the diaphragm spring (not shown) via the release bearing 18. Further, the second cylindrical member 22 follows the movement of the first cylindrical member 20.

また、図３を参照すると、クラッチディスク（図示せず）のフェーシングが摩耗してくると、油圧室１７に圧油を供給しなくても、ピストン部材１３がダイヤフラムスプリング（図示せず）の反対側に変位する。これに伴って、第１の円筒状部材２０及び第２の円筒状部材２２もダイヤフラムスプリング（図示せず）の反対側に変位する。第２の円筒状部材２２の端部が外側ハウジング１２に当接すると、第２の円筒状部材２２はダイヤフラムスプリング（図示せず）の反対側に変位しないが、第１の円筒状部材２０は変位し、第１の円筒状部材２０と第２の円筒状部材２２の間に滑りが生じ、第２の円筒状部材２２が第１の円筒状部材２０内に押し込まれる。第２の円筒状部材２２が第１の円筒状部材２０内に一旦押し込まれると、第２の円筒状部材２２は圧縮リング２１の圧縮支持により第１の円筒状部材２０内に押し込まれたままの状態になる。その後、押し込まれた状態のまま第１の円筒状部材２０及び第２の円筒状部材２２は、ピストン部材１３の移動に追従することになる。   Further, referring to FIG. 3, when the facing of the clutch disk (not shown) is worn, the piston member 13 is opposite to the diaphragm spring (not shown) without supplying pressure oil to the hydraulic chamber 17. Displace to the side. Along with this, the first cylindrical member 20 and the second cylindrical member 22 are also displaced to the opposite side of the diaphragm spring (not shown). When the end of the second cylindrical member 22 contacts the outer housing 12, the second cylindrical member 22 is not displaced to the opposite side of the diaphragm spring (not shown), but the first cylindrical member 20 is The first cylindrical member 20 and the second cylindrical member 22 are slipped, and the second cylindrical member 22 is pushed into the first cylindrical member 20. Once the second cylindrical member 22 is pushed into the first cylindrical member 20, the second cylindrical member 22 remains pushed into the first cylindrical member 20 by the compression support of the compression ring 21. It becomes the state of. Thereafter, the first cylindrical member 20 and the second cylindrical member 22 follow the movement of the piston member 13 while being pushed.

実施形態１によれば、レリーズベアリング１８より延びている第１の円筒状部材２０が外側ハウジング１２の外周面を覆うように配置されているため、クラッチハウジング（図示せず）内の汚れや埃が第１シール部材１４およびピストン部材１３の外周面への付着を防止することができる。また、クラッチディスクのフェーシングが摩耗したときにおいても、第１の円筒状部材２０及び第２の円筒状部材２２により、外側ハウジング１２の円筒状部の軸方向ラップ量を大きく取ることが可能となる。   According to the first embodiment, since the first cylindrical member 20 extending from the release bearing 18 is disposed so as to cover the outer peripheral surface of the outer housing 12, dirt and dust in the clutch housing (not shown). However, adhesion to the outer peripheral surfaces of the first seal member 14 and the piston member 13 can be prevented. Further, even when the facing of the clutch disk is worn, the first cylindrical member 20 and the second cylindrical member 22 can increase the axial wrap amount of the cylindrical portion of the outer housing 12. .

（実施形態２）
次に、本発明の実施形態２に係る油圧式クラッチレリーズ装置について図面を用いて説明する。図４は、本発明の実施形態２に係る油圧式クラッチレリーズ装置の構成を模式的に示した部分拡大断面図である。 (Embodiment 2)
Next, a hydraulic clutch release device according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a partially enlarged cross-sectional view schematically showing the configuration of the hydraulic clutch release device according to the second embodiment of the present invention.

実施形態２では、実施形態１のような圧縮リング（図１の２１）がなく、第２の円筒状部材２２は第１の円筒状部材２０の内周側で圧縮支持されない状態であってスライド可能な状態にある。第２の円筒状部材２２は円筒状部分の外周に突起部２２ａを有し、第１の円筒状部材２０は円筒状部分の内周に突起部２２ａのスライドを案内するための案内溝２０ｂを有する。第１の円筒状部材２０は、第２の円筒状部材２２が第１の円筒状部材２０から抜け落ちないようにするため、突起部２２ａを係止する係止部２０ｄを有する。第２の円筒状部材２２は、第１の円筒状部材２０の反対側の端部に、ばね部材１９と抵触しない大きさのフランジ部２２ｂを有する。第１の円筒状部材２０は、円筒状部分の外周に肩部２０ｃを有する。第２の円筒状部材２２のフランジ部２２ｂと、第１の円筒状部材２０の肩部２０ｃの間であって、ばね部材１９の内周側に第２のばね部材２３が配されている。第２のばね部材２３は、第２の円筒状部材２２と第１の円筒状部材２０を互いに反対方向に押圧する。その他の構成は、実施形態１と同様である。   In the second embodiment, there is no compression ring (21 in FIG. 1) as in the first embodiment, and the second cylindrical member 22 is in a state where it is not compressed and supported on the inner peripheral side of the first cylindrical member 20 and slides. It is in a possible state. The second cylindrical member 22 has a protruding portion 22a on the outer periphery of the cylindrical portion, and the first cylindrical member 20 has a guide groove 20b for guiding the slide of the protruding portion 22a on the inner periphery of the cylindrical portion. Have. The first cylindrical member 20 has a locking portion 20d that locks the protruding portion 22a so that the second cylindrical member 22 does not fall out of the first cylindrical member 20. The second cylindrical member 22 has a flange portion 22 b having a size that does not conflict with the spring member 19 at the end opposite to the first cylindrical member 20. The first cylindrical member 20 has a shoulder 20c on the outer periphery of the cylindrical portion. A second spring member 23 is disposed between the flange portion 22 b of the second cylindrical member 22 and the shoulder portion 20 c of the first cylindrical member 20 and on the inner peripheral side of the spring member 19. The second spring member 23 presses the second cylindrical member 22 and the first cylindrical member 20 in opposite directions. Other configurations are the same as those of the first embodiment.

次に、実施形態２に係る油圧式クラッチレリーズ装置の動作について説明する。第２の円筒状部材２２のフランジ部２２ｂが外側ハウジング１２に当接していないときは、ピストン部材１３の移動によって、レリーズベアリング１８を介して第１の円筒状部材２０及び第２の円筒状部材２２も追従して移動（摺動）する。   Next, the operation of the hydraulic clutch release device according to the second embodiment will be described. When the flange portion 22b of the second cylindrical member 22 is not in contact with the outer housing 12, the first cylindrical member 20 and the second cylindrical member are moved via the release bearing 18 by the movement of the piston member 13. 22 also moves (slids) following.

第２の円筒状部材２２のフランジ部２２ｂが外側ハウジング１２に当接している間は、ピストン部材１３の移動によって、レリーズベアリング１８を介して第１の円筒状部材２０は追従して移動（摺動）するが、第２の円筒状部材２２は第２のばね部材２３によって外側ハウジング１２に押圧力によって移動しない。すなわち、固定された第２の円筒状部材２２の外周を第１の円筒状部材２０が移動（摺動）する。   While the flange portion 22b of the second cylindrical member 22 is in contact with the outer housing 12, the movement of the piston member 13 causes the first cylindrical member 20 to follow (slid) via the release bearing 18. However, the second cylindrical member 22 is not moved to the outer housing 12 by the pressing force by the second spring member 23. That is, the first cylindrical member 20 moves (slides) on the outer periphery of the fixed second cylindrical member 22.

実施形態２によれば、第１の円筒状部材２０と第２の円筒状部材２２の間に第２のばね部材２３を配置しているため、万が一、クラッチカバー（図示せず）又はクラッチディスク（図示せず）のみを交換した場合においても、第１の円筒状部材２０と第２の円筒状部材２２を初期設定位置に戻すことが可能であり、油圧式クラッチレリーズ装置の交換または修理が不要となる。また、ストローク時（ピストン部材１３が押し出された時）に第１の円筒状部材２０から第２の円筒状部材２２が伸びるので、ダストの侵入を確実に防止することができる。   According to the second embodiment, since the second spring member 23 is disposed between the first cylindrical member 20 and the second cylindrical member 22, a clutch cover (not shown) or a clutch disk should be used. Even when only (not shown) is replaced, it is possible to return the first cylindrical member 20 and the second cylindrical member 22 to the initial setting positions, and replacement or repair of the hydraulic clutch release device is possible. It becomes unnecessary. Further, since the second cylindrical member 22 extends from the first cylindrical member 20 during the stroke (when the piston member 13 is pushed out), it is possible to reliably prevent dust from entering.
